Renewing One’s Wudhu for Each Salaah

وعن أبي هريرة رضي الله عنه قال قال رسول الله صلى الله عليه و سلم لولا أن أشق على أمتي لأمرتهم عند كل صلاة بوضوء ومع كل وضوء بسواك رواه أحمد بإسناد حسن (الترغيب والترهيب 1/222)

Hazrat Abu Hurayrah (Radhiyallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: “Had it not been for the fear of my ummah experiencing difficulty, I would have surely commanded them to make wudhu at the time of every salaah, and (I would have also commanded them) to make miswaak at the time of every wudhu.”
